Abstract
A cable head catcher mechanism for use when running tools within a well and which catches the fishing neck of a wire line operated well tool in the event the wire line should become broken due to excessive force as the well tool reaches the upper limit of its travel within the well servicing apparatus. A segmented collet system within a pressure containing housing of the apparatus is operative to catch the fishing neck of a well tool to prevent the tool from falling in the event the wire line cable becomes broken. A sleeve piston is provided which operatively positions the segmented collet within the housing and is hydraulically energized to cause releasing movement of the collet to thus release the fishing neck of the well tool when desired. The mechanism is constructed to allow the cable head and cable to be installed without requiring cutting of the cable.
